How EMI is calculated
EMI (Equated Monthly Installment) is a fixed monthly payment that covers both interest and principal. It is computed from the loan amount, the monthly interest rate (annual rate divided by 12), and the number of months, using the standard amortization formula. Early payments are mostly interest; later payments are mostly principal.
Why total interest matters
Two loans with the same monthly payment can cost very different amounts overall. A longer term lowers the monthly payment but increases total interest, while a higher rate raises both. The principal-versus-interest bar and yearly table make these trade-offs easy to see before you commit.
Payment formula and assumptions
For a positive rate, the calculator uses the standard fully amortizing payment formula: payment = P × r × (1 + r)ⁿ ÷ ((1 + r)ⁿ − 1), where P is principal, r is the annual rate divided by 12, and n is the number of monthly payments. A zero-rate loan is principal divided evenly across the term. Results assume equal end-of-month payments and no extra payments.
Assumptions and limitations
- The result covers principal and interest only. It does not include origination fees, taxes, insurance, closing costs, late fees, or lender-specific charges.
- The model assumes a fixed nominal annual rate divided into monthly periods. Variable rates, daily interest, irregular payment schedules, and promotional terms need a lender-specific calculation.
- The amortization table is an estimate. Confirm the payment schedule and annual percentage rate (APR) in the lender’s disclosure before making a financial decision.

Frequently asked questions
What is EMI?
EMI stands for Equated Monthly Installment — the fixed amount you pay each month until a loan is fully repaid. It combines interest and principal so the payment stays the same throughout the term.
Does this work for mortgages and car loans?
Yes. The calculator works for any amortizing fixed-rate loan, including mortgages, car loans, and personal loans. Enter the amount, rate, and term in months to see the payment and interest.
Is this financial advice?
No. Results are estimates for general information only. Actual loan offers may include fees, different compounding, or rate changes — always confirm terms with your lender.
